Let's get loud! Jennifer Lopez's World Cup performance is game on

HEADING TO RIO: Jennifer Lopez is set to feature in Brazil 2014's opening ceremony [GETTY]

The Play singer pulled out of the big event earlier in the week because of "production issues", but after a sudden announcement it has been revealed that she's definitely game on.

J.Lo's spokesperson said: "She will be there. Jennifer has always wanted to participate in the World Cup opening ceremonies."

Quick to refute reports that Ms Lopez had suffered a change of heart, her rep continued: "We have been trying to work out scheduling and logistics. Any statements to the contrary were premature."

Puff Daddy's ex is expected to be joined on stage by Pitbull to perform the official Brazil 2014 anthem We Are One (Ole Ola) for the climax of the opening ceremony.

On Monday, the Maid In Manhattan star's people reported: "For production issues, Jennifer Lopez, one of the artists of the official song We Are One, will not be able to perform at the Fifa World Cup opening ceremony."

It's not yet known if the Latina icon's track will live up to New Order's Italia 90 England anthem World In Motion, which has been voted the UK's top football song.

The hit – which featured a rap originally voiced by winger John Barnes – was almost twice as popular as nearest rival, Three Lions by David Baddiel, Frank Skinner and the Lightning Seeds.

New Order have outplayed their rivals, securing almost half of the votes with a whopping 41%.

Three Lions, which was released in support of the England at the 1996 European Championships, picked up 25% ahead of two tracks by Fat Les - a band made up of Blur bassist Alex James, actor Keith Allen and artist Damien Hirst.

The top five was completed with a collaboration by rapper Dizzee Rascal and actor James Corden, Shout For England.

Geordie duo Ant and Dec's 2002 attempt We're On There Ball failed to make the line-up.

Meanwhile, tax-dodging Take That star Gary Barlow scored an own goal when his record for Rio was booted out.

The former X Factor judge called upon showbiz mates Gary Linekar, Spice Girls Mel C and Emma Bunton along with Girls Aloud songbird Kimberley Walsh to help him with the updated version of Greatest Day.

Released as a part of Sports Relief fundraising campaign, the tune was made available via iTunes, but failed to score with footy fans.

A petition to get Rik Mayall's Noble England to enter the charts after his tragic death earlier this week is proving popular.

It's currently nestled at number 38, but sales are expected to soar as awareness grows on Facebook.
